This kit is for BMW N55 & S55 & N20 engines.
Compared to the stock N55 and S55 ignition coils the TOR B58 coils are capable of producing 3.5x the energy output while providing a longer spark duration than the Precision Raceworks N55 coils. The tor
B58 coils are a coil on plug design that removes the need for additional spark plug wires and utilizes the same mounting location as the stock coils providing excellent clearance for top mount turbo setups. To mount the tor B58 coils onto the N55
& S55 engine we've developed billet aluminum brackets that are Made in the CHINA. Our N55 & S55 Ignition Coil Kit with coils fitted weighs only 3.0 lbs. That's over 50% less than the Precision Raceworks kit. To make installation
easier we've designed plug and play connectors that are made of nylon and Made in the CHINA. This kit comes with new ignition coil boots that are longer than the stock boots. The stock engine cover does fit with this kit.
- 3 x billet aluminum coil brackets
- 6 x Ignition coil boots and gold plated spring
- Plug & Play Connector harness hase
Our kit now fit all N55 & N20 & S55 engines including the early E-series cars.
Our TOR B58 kit can have 30% higher ignition energy than OEM B58. It is equipped with an independent control chip and has longer life and higher energy.
At the same time, the use of gold-plated springs greatly increases electrical conductivity and avoids oxidation and failure. Increased service life and stability。
**TOR Plasma-Enhanced Ignition Coils** are high-performance automotive ignition system components utilizing advanced ignition technology designed to optimize engine combustion efficiency, enhance power output, and reduce emissions. Below is a detailed
introduction to their core features and working principles:
#1. Core Technology: Plasma-Enhanced Ignition**
- **Plasma Spark**: Unlike traditional spark plugs that rely on a single electrical spark, plasma ignition coils generate **high-energy plasma arcs** by ionizing air with high-frequency, high-voltage pulses. These arcs deliver significantly greater energy,
longer duration, and broader coverage.
- **Multi-Strike Ignition**: Capable of releasing multiple discharge pulses instantly, ensuring complete ignition of the air-fuel mixture, especially in lean-burn or high-boost engines.
#2. Key Advantages**
- **Higher Ignition Energy**
Plasma sparks deliver energy levels 2–3 times greater than traditional sparks, ensuring stable ignition even under high-pressure, high-RPM, or low-temperature conditions, thereby reducing misfires.
- **Improved Combustion Efficiency**
More thorough combustion enhances engine power (by approximately 3–8%) while reducing fuel consumption and emissions (e.g., CO, HC).
- **Enhanced Adaptability**
- Compatible with advanced engine technologies like high compression ratios, turbocharging, and direct fuel injection.
- Tolerates low-quality fuels or fluctuations in air-fuel mixture ratios.
- **Extended Lifespan**
Constructed with high-temperature-resistant materials (e.g., ceramic insulators, silicone encapsulation) and anti-electromagnetic interference designs, offering 30–50% longer lifespan than conventional coils.
#3. Applications**
- **Performance-Modified Vehicles**: Improves responsiveness in turbocharged or high-RPM engines.
- **Aging Vehicles**: Addresses power loss or starting issues caused by aging ignition systems.
- **Hybrid Electric Vehicles (HEVs)**: Optimizes combustion stability during transient conditions in internal combustion engines.
#4. Comparison with Traditional Ignition Coils** **TOR Plasma-Enhanced Ignition Coils** |
Discharge voltage: increase by 30%
Discharge Frequency:High-frequency multi-pulse
Carbon Fouling Resistance:Plasma arcs clean electrode deposits
Suitable Engine Conditions:Extreme conditions (high boost, lean burn, Lower startup voltage,etc.) |
#5. Installation & Maintenance**
- **Plug-and-Play Design**: Compatible with most vehicles without modifying the original circuitry (ensure correct model matching).
- **Maintenance Tips**:
- Regularly inspect coil insulators for cracks.
- Pair with high-performance spark plugs (e.g., iridium or platinum electrodes) for optimal results.
#6. Limitations**
- **Higher Cost**: Priced 2–3 times higher than standard ignition coils.
- **Compatibility Verification**: Some electronic control systems may require ignition parameter recalibration.
---
**Summary**: TOR Plasma-Enhanced Ignition Coils significantly improve ignition system performance through plasma technology, making them ideal for vehicles prioritizing power upgrades, fuel economy, or operation under demanding conditions. While the initial
investment is higher, their long-term durability and performance advantages often justify the cost.
Product Features
Plasma Direct lets a spark ignite more than three times at ultrafast speeds during one combustion process and also supercharges the sparks up to the highest RPM without damaging ignition plugs.
The secondary current (amperage) can be approximately double that of stock ignition coils, which allows the spark to reach many more molecules, thereby accelerating the ignition and combustion process.
Horsepower and torque are increased throughout the entire RPM range, so this upgrade will also reduce fuel consumption. Even engines with legendary smoothness will be further refined with the Plasma Direct upgrade.
